The process of acquiring a language involves a complex interplay of the child's own cognitive capabilities with their unique social and language environment. My research focuses on building a comprehensive model of the normal processes of early language acquisition. My research foci revolve around three domains of inquiry: 1) determining how infants' developing perceptual skills influence their burgeoning linguistic knowledge, 2) understanding how different social contexts and the dynamics of caregiver-infant interactions influence the language environment of infants and toddlers, and 3) understanding the role of the environment in determining language acquisition outcomes.
